i'v built 460 big blocks and made a stand out of 4 by 4, its not hard. just make a panel to hold gauges and extra radiator for cooling. you can break it in and also check and repair any leaks easier plus make your final valve adj easier. with new cam etc you should run at least 1500 to 2000 for 15 min and seat your lifters to cam.( now computer systems i;v never done them.) then when install can get on.
